The South Korean automaker says in government documents that a wind deflector anchor plate in front of the sunroof wasn't bonded properly to the car. A loose deflector can detach and interfere with the roof as it closes. If the owner tries to force the roof closed, it can fly off.

The company says it has no reports of accidents or injuries due to the problem. But Hyundai had several reports of detached sunroofs in the U.S.
